Schendel | July 3, 2001 |
An electrical system is disclosed which includes a supply voltage and electronic circuitry which requires an operational voltage that is less than the supply voltage. A thermoelectric heat pump is interposed between the supply voltage and the electronic circuitry to produce heating or cooling using the excess power which would otherwise be dissipated in a regulator. A voltage regulator is provided between the output of the thermoelectric heat pump and the electronic circuitry to provide the operational voltage to the electronic circuitry.
